CRUDE-oll. BURNER'.

l SPECIFICATION forming part of Letters Patent No. 703,706, dated July 1, 1902.

` Application led November 23, 1901. Serial No. 83,468. (No'model.)

T0 all whom it may concern:

Be it known that I, JOHN AUGUsr'MEYER, a citizen of the United States, residing at 128 Ferris avenue, in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Crude-Oil Burners; and I do hereby declare the following to be a full, clear, and exact description of said invention, suchV as will enable others skilled in the art to which it Inost nearly appertains to make, use, and practice the same.

This invention relates to improvements in crude-oil burners in which the oil is ejected by steam-pressure. This class of burners has hitherto been subject to the disadvantage of In the drawings, Figure 1 is a side eleva-l tion of a burner constructed in accordance with this invention. Fig. 2 is a longitudinal cross-section of the same,the perforated steam pipe and collars thereon being shown in full lines. Fig. 3 is a vertical cross-section on the line Fig. 2.

In the description with reference to the drawings similar letters o f reference applyk to similar parts throughout the various views;

Inconstruction the invention, consists of the T member A, a solid block` of metal cast in the form shown having the internal bore A', into which the steam-pipe B is screwed in the rear, and the oil-pipe C, screwed into the annular extension'Azat'the bottom, both leading into the barrel A5. 'Screwed into the forward opening of thebore A', forminga continuation of the same, is the pipe A3, terminating in the tip A4. Screwed into the 'bushing D', screwed into the bore A', abutting the steam-supply pipe B, is the perforated steampipe D, upon which at intervals are rigidly secured the perforated annular collars D2.

The end of the perforated steam-pipe D is closed by the plug D3. The burner is preferably constructed throughout of brass or bronze, as best calculated to withstand corrosion and heating.

In the operation of the burner the best results are obtained by feeding the oil under 6o pressure. This may be accomplished by a number of well-known methods-such as the Water-lift, tc-gravitation being unreliable. The steam blowing through the perforations D4 in the pipe D mixes with the body of oil surrounding the same, forming an intimate admixture, dividing the oil into atomic particles, which are kept violently agitated in their passage through the perforations D5 in the various collars D2, issuing through the last of these into the tip A4, from which it escapes intoian atomized'spray which burns without soot, the combustion being clear and transparent. In thus mixing the steam (or air) with the oil before ignition it is possible to cut the flame down to any desired volume by regulating the proportion of steam and oil respectively controlled by the valves B' C'. It has been demonstrated that this burner can throw a iiame reaching under a boiler and back through the tubes or can be shut down to a mere pilot-light, the quality of iiame being the same in each instance. This is not possible in burners dependingupon the mixture of the steam and oil after liberation.

I-Iaving thus described this invention, what, I claim, and desire to secure by Letters Patent, is-

Anoil burner comprising the following partsto wit: a, barrel terminating in a discharge-tip, a pipe having numerous perforations and of appreciably smaller size than said barrel and located therein, perforated collars locatedl at intervals on the perforated pipe and extending between the pipe and the barrel, means for supplying oilto the interior of the barrel and-around the perforated pipe, and means for supplying steam toth'einterior of said perforatedpipe. l

In testimony whereof I have hereunto set my hand this'22d`day of October, 1901.

JOHN AUGUST MEYER.
